Tl-lRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No..264,294, datedSeptember 12. 1882,

Application filed October 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN HUGHES, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Thraslring-Machines; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to the letters or figures of referencemarked thereon, which form a part of this specification.

My invention relates to a combined thrasher, band-cutter, straw-carrier,and separator; and the novelty consists in the construction andarrangement of parts, as will be more fully hereinafter set forth, andspecifically pointed out in the claims.

The invention is fully illustrated in the accompanying drawings, whichform a part of this specification, and in which- Figure 1 is a plan,partly in section. Fig. 2 is a central "ertical longitudinal section;Fig. 3, a left elevation; Fig. 4, a right elevation; Fig. 5, afrontelevation; Fig. 6, a plan of the bottom, and Fig. 7 a detail of amachine constructed in accordance with my invention.

Referring to the drawings,in which the same letters of referenceindicate the same or corresponding parts in all the figures, Arepresents the irame,'in which is journaled, at b, the shaft b of arevolving beating-cylinder, B, having beating-teeth b arranged uponlongitudinal beams secured at each end to one of the cylinder-heads, thearms on each succeeding beam being situated opposite the space betweentwo arms on the preceding beam, so that during each revolution of thecylinder all portions of the concave located beneath it will be passedover or traversed by the arms. The shaft 1) may be provided with apulley, D which is adapted to be belted to a pulley, 0, upon acrank-shaft, U,Fig. 2, upon the crankarms of which are pivoted levers c,which operate the shoe D. To this shoe are secured metal straps d d,which support it in such a manner that it can be vibrated.

To the front strap, d, at its point of attachment to the shoe, ispivotally secured a link, (1 which connects pivotally with an arm, dpivoted at d to the frame A, and a link, 01'', connects pivotally with ahorizontal arm, at, as shown. The arm 61 is connected by a crankarm, 6,at two or more places with rock-shafts E, carrying arms or forks c, asshown. It will be observed that this construction of parts not onlyvibrates the shoe, but that as the shoe recedes the pitching arms orforks e have at their free ends a quick motion in the oppositedirection, and vice versa, on account of the increased length of saidforks over that of the arms 0.

A modification of the system of connections between the vibrating shoeand the pitchingarms is shown upon the opposite side of the machine inFig. 4 ot' the drawings, wherein the arm d is connected directly withthe rear shoe-supporting strap, (1; or it may be connected to the shoeby a slotted strap, d piv oted to the frame at d.

Inclined chutesfreach through the heads of the beating-cylinder B, andare provided with inwardly-projecting similarly-inclined flaringmouth-piecesf, which serve to induce a current through a channel, F,formed in the frame A, the exit of which is above or below the vibratingscreens in the shoe, as may be desired.

In Fig. 5, H represents a transverse board, which is adjustablevertically by means of the holes h, or any other convenient means, andit carries the band-cutters h in such a manner that the said cutters maybe placed in or out of operation at will by reason of the adjustment h.The band-cutters h project through kerfs'i in a feed-board, I, pivotedat i, and adjusted at will by a crank-shaft, i having external arm, J,operating in a proper segmental rack. This construction allows thefeed-board to be elevated or depressed at will, and to thus expose moreor less of a toothed or serrated portion, K, which serves to retard thefeed of grain by engaging the lower portions thereof, and by reason ofthe friction between the straws or stalks of the gavel.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In a thrasher and separator, a cylinder provided with arms arrangedin the order described, and rigidly connected to the cylinder, combinedwith a stationary retarding device and a concave perforated as shown,and hav- 5 ing no stationary arms, as specified.

2. In a thrasher and separator, the combination of a shoe adapted to bevibrated, a series of forks secured to roeleshafts, a bar connecting thearms of the rock-shafts, and a link pivoted to the frame-work andconnected to saidbar and to the shoe, substantially as shown anddescribed.

3. The combination of the forks c, secured to the rock-shaft E, the arms0, the bar 61 lever d pivoted to the frame-Work, and the shoe 1),substantially as shown and described.

4. The combination of the feed-table I, pivoted at i, the crank-shaft tthe fixed retardin g device K, the toothless perforated concave B, andthe cylinder B, substantially as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN HUGHES.
